General Characteristics
The MXL 990XL has a 6-micron, gold-sputtered diaphragm and a fixed
cardioid pickup pattern. Condenser microphones are very sensitive and
reveal very subtle sonic details. They also tend to pick up sounds from
outside the pickup pattern more than some other designs do, which can
lead to powerful feedback if you are not careful.
We recommend that you experiment with the microphone’s placement and
isolation, with the gain initially set low to avoid damage to your equipment
and hearing. We also recommend that you use a mesh pop filter to
prevent moisture from damaging the microphone’s capsule.

The MXL 990XL requires 48V phantom power (± 4V). If no sound is picked
up by the microphone, make sure that the phantom power on your mixer
or separate power supply is switched on.
Microphone Cable
The microphone cable can have a profound effect on the sound of
any microphone. Even the finest microphone will sound poor if the
interconnect cable allows noise to enter or causes distortion and loss of
information. We recommend that you use the best microphone cable that
your budget will allow.
Care
Dust and foreign material can reduce the performance of a microphone
over time, so you should store the MXL 990XL in its case when not in use.
